rename Generator to Coroutine
implements https://github.com/rust-lang/compiler-team/issues/682
While I did an automated replacement, I went through all changes manually to avoid renaming things like "id generators", "code generator", ...
I renamed files where that was necessary due to the contents referring to the crate name itself (mir opt, codegen or debuginfo tests), or required by tidy (feature gate docs)
* [x] rename various remaining abbreviated references to generators.
* [x] rename files
* [x] rename folders
* [x] add renamed feature: `generators`, ...

Restructure `rustc_type_ir` a bit
1. Split `sty` into new `ty_kind`/`region_kind`/`const_kind` modules, so that when we uplift more kinds (e.g. `PredicateKind`, `ClauseKind`, and `ExistentialPredicate`), they can live in their own simple-to-understand files.
2. Split up the `structural_impls` module, which is a kitchen sink of random impls -- move `TypeFoldable` and `TypeVisitable` impls into existing `fold` and `visit` modules, respectively.
3. Move the `DebugWithInfcx` trait and blanket impls into a new `debug` module, and `TypeFlags` definition into a new `flags` module.
5. Move `Interner` trait into a new `interner` module. I expect this file to get a lot larger as we make the interner more powerful for the trait solver refactor.
r? `@ghost` for now, will assign once #116946 lands
Move where doc comment meant as comment check
The new place makes more sense and covers more cases beyond individual statements.

Uplift movability and mutability, the simple way
Just make type_ir a dependency of ast. This can be relaxed later if we want to make the dependency less heavy. Part of rust-lang/types-team#124.

Add a test showing failing closure signature inference in new solver
Been thinking a bit about how to make this test pass... but we don't actually have any good tests exercising this behavior in the suite.

Specialize `Bytes<R>::next` when `R` is a `BufReader`.
This reduces the runtime for a simple program using `Bytes::next` to iterate through a file from 220ms to 70ms on my Linux box.

Fix duplicate labels emitted in `render_multispan_macro_backtrace()`
This PR replaces the `Vec` used to store labels with an `FxIndexSet` in order to eliminate duplicates

intptrcast: remove information about dead allocations
The discussion in https://github.com/rust-lang/miri/pull/3103 convinced me we don't have to keep `int_to_ptr_map` around for dead allocations. But we should not make that depend on the GC, we can just tie it to when the allocation gets freed. That means everything still behaves deterministically, if anything weird happens (but it shouldn't).

Only the first and last commit contain logic changes, the 2nd commit just moves code around a bit.
Implement rustc part of RFC 3127 trim-paths
This PR implements (or at least tries to) [RFC 3127 trim-paths](https://github.com/rust-lang/rust/issues/111540), the rustc part. That is `-Zremap-path-scope` with all of it's components/scopes.
`@rustbot` label: +F-trim-paths
Add FileCheck annotations to mir-opt tests.
This PR makes compiletest run LLVM `FileCheck` tool on mir-opt tests.
The check is *run by default*, except if disabled using `// skip-filecheck` comment. This ensures that we do not have a silently broken test. For now, the check is only run on the output of `--emit=mir`, ie. on PreCodegen MIR.
I give an example on `reference_prop.rs`.
